First off I wanted to say how much I love your UI. I prefer the squared edges as opposed to the rounded as I can arrange things a little better on my screen.

With regard to the Target Window, would it be possible to enlarge the border around the target so that you can see the color con better? I know that once you are fighting and the mobs health is going down, you can see if it's dark blue, yellow, etc. But when you initially con the mob it is sometimes difficult to tell what the con is.
